To all wwm it may concern:

Be it known that l, Banni H. TUTTLE, a citizen of the United States, and a resident of Absarolrce, in the county of Carbon and State of Montana, have invented certain vnew and useful Improvements in Haystackers., of which'the following is a specication.

iuns

My invention relates to hay stackers of the type embodying a base having a frame pivoted thereto for swinging movement from horizontal to vertical positions, whereby hay or other material deposited upon a fork carried by said pivoted-frame may be elevated 4and stacked, and it is my purpose to improve hay stackers of this type by providing an adjustment for the fork whereby.

v and which is so connected with the stacker that when the pivoted frame approaches a' substantially verticalposition said fork is tilted to thereby assure the hay which is carried thereby being turned over and completely delivered therefrom. onto the stack in an untangled condition; Furthermore, in this connection it is a purpose of my invention to provide a tilting arrangement for the fork which will cushion the latter when it is tilted to thereby relieve the stacker of strains due to sudden starting and stopping of its movable parts. y

My inventive idea is capable of embodiment in various mechanical structures one of which is illustrated in the accompany-ing drawings, but it is to be understood that the tstructure shownV ismerely-intended as a disclosure of the essentialfeatures and-novel characteristics of my invention in a preferred form and that its scope is as defined in the appended claims.

In the drawings wherein like characters of reference denote corresponding parts in the different views- Figure lis a. perspective showing the nor-V mal relation of parts of my improved stacker; L Fig. 2, a

longitudinal Seann-.arma an saine showing the elevated position @t an pivoted frame and the fork tllted;

Flg. 3, a fragmentary View similar to Fig.

2 showing the fork and related parts in the positlon they occupy during elevation of the pivoted frame andas the latter approaches a vertical position; and

Fig. 4, an enlarged perspective of one of the tilting arms for the fork.

Referring now to the drawings in detail, it will be observed that my improved stacker consists essentially of a base 10 and a frame 11 which latter is pivoted to the base for swinging movement from a normal horizontal position as shown in Fig. l/to a vertical or substantially vertical position as shown in Fig. 2, and viceversa.`

The base 10is composed ofy a pair of beams 12, 12 secured together in parallel spaced relation by transverse beams 13 and 14 at r near the ends thereof respectivel and br d by the diagonal bars 15, while t e frame 11 iscomposed of a pair of parallel beams`16, 16 which are secured together in spaced relation near their free ends by a transverse beam 17 and which are pivoted at their other ends to the beams 12, 12 on the outside of the frame 10 as shown. The transversev beam 17 extends beyond the sides of the beams 16, 16- and has its ends connected to the latter beams byv braces 18. y

. Pivoted -inside ofthe base 10 to the beams 12, 12 near `the transverse beam 13 are the lower ends of a pair of beams 19, 19 which are arranged in upwardly converging relation and at their free ends are'secured tcgether as at 20 where they have pivotalcon- Y nection with a pair of downwardly .diverging rods 21, 21 which are connected at their lower endsto the beams 16, lrespectlvely next to the `transverse beamI 17. A pulley block 22 is vsecured to the transverse beam 14 of the base and an operating cable or rope 23 is trained over this pulley and connected to the upper end of the frame constituted by beams 19, 19;'

Carried by the frame 11 at its free eno 1s a' fork 24. consisting essentially of two series of tangs 25 and 26 constituting what ma be termed the bottom and rear of the for respectively.' The tangs 25 are secured to'- gether in parallel spaced relation by apair 'of spaced, relatively light transverse beams thereby rel? while the 27 and'28 and are maintained atively and rigidly assembled,

tan s 26 are also secured. to ether in paralle spaced relation by 'an intermediately disposed, relatively light transverse beam 29 and at theirinner ends are pivotally connected to the transverse beam 28 so that the bottom and back of the fork may be moved angularly with respect to each other. as is apparent. Links 30 connect the free ends of the beams 16, 16 of frame 11 with the transversel beam 27 of the bottom of the fork whereby the latter at predetermined times is moved laterally with respect to and above the frame 11 as shown in Fig. 2 of the drawings.

One or more tilting arms 32, two being shown in the present instance, are pivoted intermediately to the transverse beam 17 of frame 11 and at one Aend are pivoted respectively to a pair of members 33 extending inward from the bottom of the fork, while at their other or free. ends they are rounded and `each has slidably mounted thereon a plate 34 which is normally maintained at its inward limit of movement by a coil spring 35 disposed betweensaid plate and a head on the adjacent end of the arm. A cord or cable 36 of predetermined length connects said plates 34 with a portion of the base 10 such as thetransverse beam 13.

Extending rearwardly from the back of the fork are two slotted plates 37 and pivoted to said plates and adjustable along theslots therein by means of bolts 37 are the forked ends of a pair of light beams 38 which at their opposite ends arepivotally connected to the respective beams 16, 16. By adjusting 'the first mentioned ends of said beams 37 in the slots ofplates 36 the angular relation of the bottom' and rear or back of the fork may be varied.

The normal relation of the parts described in the foregoin is shown in Figure 1 of the drawings in w ich material to be han led or stacked is deposited on the fork in any suitable manner, after which a ull is exerted on the cable 23 eithervmanually or otherwise to swing the frame 11 to a vertical or substantially vertical position as shown in Fig. 2 to elevate the fork and the hay "j arried thereby, it belng apparent that a pull on cable 23 serves to swing the frame composed of beams 19, 19 downward and thereby exerts an upward pull on rods 21,121 to elevate the frame 11. Normally the bottom ofthe fork is so dispOSed that it constitutes in effect a continuation ofthe frame 11 and this relation of the fork and frame is maintained during the upward movement of the lattei'as shown in Fig. 3 until said kframe reaches the vertical position of Figure 2. However, as frame 11 in its upward movement approaches the' vertical, cord 36 becomes taut and exerts a pull on the free ends of arms 32 which latter then swing about their inosition hay or otherkk pprtions links pivotally connecti substanti ally termediate pivots and serve to push thefork bodily outward or upward and also laterally with respect to the frame 11 with a quick, sharp movement tending to throw the hay from the fork, rearward or lateral movement being imparted to the fork by lswingin movement of links 30 resulting from upwar movement of the fork with respect to frame 1l as is manifest, while at the same time the free end of the rear or back of the fork is tilted downward due to the upward movement of the inner ends of tangs 26 with the bottom tangs 25 and to'the fact that the outer ends of tangs 26 cannot move up with tangs 25 because of their connection throu h parts 37, 38 with the frame 11. If it is esired to drop hay from the fork at the near side of a stack an adjustment between parts 37, 38 is made by means of the slots in members 37 and the bolts 37 carried by members 38 so that the back of the fork w1ll slope downward when the frame 11 is elevated, and if it is desired that the hay be thrown to the top or far side of a stack an adjustment is made as aforementioned so that the rear of the fork will be disposed horizontally or at an acute angle with respect to the tangs of the bottom of the fork, all as is apparent and is believed is well understood.

As the cord 36 becomes taut the plates 34 ride down the rounded ends of the arms 32 and compress the springs 35 thereby cushioning the tilting movement' of the fork and as is apparent this cushioning of the fork and the manner of connecting the parts of the stacker serves to initiate return of the frame 11 to normal horizontal position following its elevation.

From the foregoing description otaken in connection with the accompanying drawings, it is believed that the construction operation and advantages of my im roved stacker will be clearly understood an while I have herein lshown and described one specific embodiment of my invention I'do not confine myself to the detail arrangement shown as various modifications and changes may be made in and to the same within the scope of my invention as defined inthe appended claims.

1. A stacker for ha and other materials including a base, a ame pivoted to said base for swinging movement, a fork comprising relatively pivoted bottom and retr ame with the bottom portion of sai fork,

and means for moving the fork longitudinally of the frame when the frame is swung .with respect to the base whereby tiltin -movement is imparted to the fork by sai links.

2. A stacker for ha including a base, a e pivoted to said base for swinging movement, a forkcarried vand other materials` iframes? by said frame, and connections between the g :trame and fork and between the fork and the base whereby the fork is moved bodily longitudinally and laterally with respect to the :trame during swinging movement of the latter 3. A stacker for hay and other materials comprising a base, a frame pivoted thereto for swinging movement, a fork comprising relatively pivoted bottom and rear portions, a link pivotally connected at one end to the frame and at its other end to the 'bottom portion of said fork, an arm pivoted intermediately to the frame and at one end to the bottom portion of said fork, and a fiexible element of limited length connecting the other end of said arm with the base whereby a predetermined amount of swinging movement of the frame with respect tol the base imparts rotation to said arm to move the fork longitudinally with respect to the frame and thereby cause the aforementioned link to. move the fork laterally with respect to the frame.

4. A stacker for hay and other materials including a base, a frame pivoted thereto for swinging movement, a fork, an arm pivoted to the frame and connected to said fork, an element connecting said arm to the base whereby swinging movement of the frame imparts tilting movement to the fork, and a yieldable connection between said elementv and said arm whereby tilting movement of the fork is cushioned.

5. A stacker for hay and other materials including a base, a frame pivoted thereto Jfor swinging movement, a fork pivoted to said frame, an arm pivotally carried by the frame and connected to said fork, av member slidable on said arm, a sprin normally urging said member in the directiion of the pivotal connection of the latter with said frame, and an element connecting said slidable member to the base whereby swinging movemnt of the frame imparts rotation to said arm to tilt the fork relative to the frame, said member being adapted to slide on 'said arm andv compress said spring during tilting movement of the fork to cushion the same.

In testimony whereof I `hereunto affix my signature. l
